During the Clone Wars, the Impavid[4] served in Coruscant Home Fleet, which was the defense fleet for the Republic's capital world of Coruscant.[5] In 19 BBY, towards the very end of the war, the Confederacy launched a full scale attack on the Coruscant system, catching the Republic unprepared. The Impavid itself was in orbit over Coruscant when the battle started, with dozens of Separatist cruisers and warships exiting hyperspace around the Star Destroyer. However, there were too many Separatists ships around the Impavid for the destroyer to avoid, and the Impavid was hit on its left side by a Confederate Providence-class carrier/destroyer leaving hyperspace. The collision heavily damaged the Republic vessel, with its bow trailing a large amount of fire and had the ship's hull beginning to tear apart.[2]

The collision between the two ships was witnessed by High Jedi GeneralSaesee Tiin, who was flying in his personal Jedi starfighter, having taken command of the Republic's space defense. General Tiin landed in the doomed Impavid's main hangar, where the ship's clone commander informed the Jedi Master that the Star Destroyer was lost and needed to be abandoned. Tinn decided to take command of the Impavid, coming up with a plan to escape the failing vessel.[2]

Clone marines and General Tiin jump out of the Impavid.

The Jedi General ordered the Impavid to pass over a nearby Separatist cruiser, the Providence-class carrier Prosperous, with the Impavid firing its turbolasers at the Separatist cruiser. After donning pressurized space suits, Tiin and hundreds of the Impavid's clone marines jumped out of Impavid's left side hangar, towards the Prosperous. Flying through debris-filled vacuum, Tiin and the clone marines landed on the Prosperous's hull, and—fighting their way into the Confederate capital ship—managed to capture the Prosperous[2] and return to Coruscant.[6]

At the time of the Battle of Coruscant, the Impavid was crewed by hundreds of elite clone marines, led by a clone commander. After the Impavid was damaged during the battle, Saesee Tiin took command for a short time, ordering the Impavid's clone troopers to abandon the failing destroyer and to seize the Prosperous.[2]

In the Clone Wars episode, when the Impavid is shown being hit by the Separatist cruiser coming out of hyperspace, it appears to be ripped in half by the collision. However, in the very next scene, the Impavid is shown—although heavily damaged—in one piece. For the rest of the episode, the Impavid is drawn as one full ship, and due to this, this article assumes that the Impavid remained intact during the events of the episode.
